My fingerprint reader is 'not working' any more.

Hi Arch Linux Comunity!

I have a problem with my fingerprint reader (VFS0050), some days ago it just stopped working.
It was working fine, I was using it with my three-factor authentication (3FA) system.
I did not change something in the system or install something new.

When I try to use the fingerprint reader with 'frprintd-enroll' or try to setup a fingerprint with Gnome, the fingerprint reader led just turns ON for a second and then stop working. (No red/orange led light)
There is no error message or something else, the terminal is waiting for me to enroll my fingerprint.

[davidpj@encryptedgarage ~] $ fprintd-enroll
Using device / net / reactivated / Fprint / Device / 0
Enrolling right-index-finger finger.

I tried to check the system logs but I didnt found something, however if you need me to show you something, just ask me for it!
I know that I'm not giving too much information, but I have no idea what kind of information I need to show! I'm sorry about that!

The fingerprint is working fine on Windows 10 and Kali Linux.

I have searched on internet but I didn't find something useful
If anyone can give an idea where i can check what is going wrong here, will be amazing!

PD: I didn't know where to post this topic, 'Kernel & Hardware'?, 'Laptop issues'?, 'Newbie Corner'?, so I'm sorry if this is not the right place!

Thanks for your time and help!
